SPECIFICATION fermingpart of Letters Patent No. 284,209, datednseptember 4, i883.

" Application led June 9, 1883. (No model.)

To all whom,` it may concern/ Be it known that I, 'WILLIAM J. JACKSON,

a citizen of the United States, residing .at Osceola Mills, in the county of Clearfield, State of Pennsylvania, have invented a new and useful Improvement `in Car-WheelAxle Lubricators, which improvement is fullyset forth y, L in the following specification and accompanyy Figure 1 is a front view of a car-wheel-axle lubricator embodying `my invention, the cap being removed. Fig. 2 is arearview thereof. Fig. 3 is a diametrical section thereof, the cap being in position.

Similar letters of reference indicate .L corresponding parts inthe several figures.

My invention consists of a car-wheelaxle lubricator in which the hub L is strengthened, the axle continuously and l uniformly lubricated, the'escape of the lubricant and entrance of dirt are prevented, and a collar is provided for connectinguthe wheel andl axle, the same hereinafter set forth. i

Referring to the drawings, A'represents a car-wheel, inthe hub B of which is formed a chamber, B', which extends parallel with the axis of the wheel and' encircles the bearing being lubricated and inclosed, all as will be t portion B of the hub; C represents radial partitions, which are formed with the bearing portion B and outer wall of the chamber, serving to unite said parts and divide the chamber t into sections. The front end of the hub is formed with a neck, D, which is threaded for engagementof ascrew-cap, E, the latter closing said end, and forming a chamber, E', for the reception of the lubricant, lit being noticed that said cap is in communication with the chamber Biof the wheel througlnthe slots or ducts a in the front wall of the neck. The inner end `of the hub is closed by awall, F, in which is a `the chamber B, by means of a cap, Gr, which is `screwed or bolted to `the hub,and contains within it a collar, H, formed on or secured to 3 Vthe axle of the wheel, it being evident that dirt isv prevented from reaching the chamber b and `with the chamber B, and the central opening or bore of the hub for` directing the lubricant to the axle which occupies said opening.

In the center of the cap Eis an opening or inlet, d, for supplying the chamber E with lubricant, said opening being closed by a valve,

J, which occupies a position withinsaid chamber, and is pressed against its seatby aspring,

i K, one end whereof bears against the valve, an d `the other .end bears against wires or rods L,

which are secured to lugs M, formedontheim ner face of the cap. The lugs Mare disposed at intervals, or a single annular lug may be employed, and the wires or rods L inthe present case are attached to the lug or lugs during the operation of casting the cap and lugs, and crossed or meeting centrally, so as to form a bearing for the spring, thus providing a cage for the valve and spring, the samev occupying but a small portion of the chamber E' of the cap. The chambers E B are supplied with oil or lubricant through the inlet d, the Valve J being forced back, so as to open and .uncover `said inlet, 'after which the valve is permitted to close, so astoprevent the escape of the lubricant and entranceof dirt into the chambers.

As the wheel revolves,the lubricant reaches the axle through the slots at, and thus continually and uniformly lubricates said axle, the escape of the lubricant around the axle on the inner end of the hub being prevented by the wall F.

`The ducts a, however, `dirctthe lubricant from thechamber B to the chamber b of the cap G, whereby the collar H and portion of the axle in contactwith said cap are fully and `the Wheel and aXle, and obviates linchpins chamber, said Walls, neck, and partitions bepartment is continuously supplied, the slots c being thereby filled and continuously directing the lubricant to the axle.

The collar H being encircled by the cap G, which issecured to the hub, serves to connect and-other fastenings.

AThe partitions G, connecting the bearing B and outer Wall of the chamberB, as has been stated, provides the sustaining-Walls for the hub through said chamber from end to end of the hub, the entire length of the bearing portion thus being supported by said partitions, andV adapted to endure the severe usage to Whiehzit is subjected.

Having thus described my invention, what I claim as new, and desire to' secure by Letters Patent, is-

1. In an aXle-lubricator, a Wheel having a chamber or reservoir encircling its central bearing portion, and a threaded neck, D, projects forwardly from the center' of the hub, in combination with ascreW-cap Which engages With said forwardly-projecting neck, substantially as and for the purpose set forth.

2. A screw-cap, in combination with the Wheel, having a reservoir encircling the central bearing portion thereof, a threaded neck projecting forward from the hub, and radial partitions Whichjoin the front wall of said projecting neck and inner or rear Wall of the hub, and the inner and outer walls of the lubricanting cast together, substantially as and for the purpose set forth.

3. In a car-axle lubricator, the cap C, pro- With Wires which are connected With said lugs,

the Wires and lugs forming a cage for said valve and the closing-spring thereof, substantially as and for the purpose set forth.

4. An axle having a collar, H, in combination with a Wheel having a central lubricantreservoir, C, and at each end a cap forming the chambers E Z, the front Wall of said reservoir having ducts a', leading from the chamber E into the reservoir C, and the rear Wall having duct a, leading from said reservoir into the chamber b, substantially as and for the purpose set forth.

5. The axle having a collar, II, in combination with the Wheel. having a reservoir, B', a forwardly-projecting threaded neck, D, and radial partitions C, the front screw-cap, E, With a valve, the innercap, G, the front Wall of the neck D having ducts a, and the rear Wall of the hub having ducts c, the Wheel, with the neck D and partitions C, being cast together, all substantially as and for the purpose set forth.

WILLIAM J. JACKSON.
